Hi @gjtempleton, @MaciekPytel
PTAL!

[Shubham82]

Previously few test cases failed because somehow I missed the pre-commit hook things, update the PR according to that.

[Shubham82]

Now only Lint and Test Charts / Helm chart (pull_request) is failing, why is so?

on checking the details of the test case it is showing the following error:

Linting chart 'cluster-autoscaler => (version: "9.28.0", path: "charts/cluster-autoscaler")'
Checking chart 'cluster-autoscaler => (version: "9.28.0", path: "charts/cluster-autoscaler")' for a version bump...
Error: Error linting charts: Error processing charts
Old chart version: 9.28.0
New chart version: 9.28.0
------------------------------------------------------------------------------------------------------------------------
 ✖︎ cluster-autoscaler => (version: "9.28.0", path: "charts/cluster-autoscaler") > Chart version not ok. Needs a version bump!
------------------------------------------------------------------------------------------------------------------------
Error linting charts: Error processing charts
Error: Process completed with exit code 1.

but the latest chart version for CA is already 9.28.0. did I miss something here?

@gjtempleton could you please take a look?

Old chart version: 9.28.0
New chart version: 9.28.0

is the problem. You need to bump the chart version to 9.28.1 as it can't publish a new chart otherwise.

@gjtempleton, could you please tell me why we have to change it to 9.28.1

We use automated tooling to build and publish the releases of the helm chart: https://github.com/kubernetes/autoscaler/blob/master/.github/workflows/release.yaml#L4-L29

It does this based on the chart-version declared in Chart.yaml, so on merging a PR updating the chart and the chart version, it will create the release, and publish the associated tarball, as well as updating the gh-docs branch to allow discovery of the new version of the chart.

Thanks for the above info.

Hi @gjtempleton
As CA 1.27.0 / 1.27.1 has been released so should I update the chart version to 9.29.0 and appVersion to 1.27.1?

[Shubham82]
